I'm about to buy my first DSLR and I'm trying to understand every single aspect of it.

If I've got a prime lenses and I'm shooting a video with 2f/2.8 aperture, I'm going to have a fixed depth of field  (1nearest point of focus in which1. nearer points where sharpness is acceptable, 2focus2. actual focus point and 3further point of focus3. points further away in which sharpness is acceptable). So when I turn the focus ring what is happening to these three factors 1,2,3 mentioned above, technically? Is this fixed depth of field moving forward and backward linearly for the actor/object to be kept in focus while in movement?

I've been trying exhaustively to find this specific information here, on google, videos on youtube but I can't find the straight answer for my question.

Thanks

What exactly happens when one turns the focus ring on a DSLR while shooting video?
